Coming off a season in which he missed about two months with an oblique strain and had minor right knee surgery this winter, Chen said health is his number one goal, and he also would like to pitch more innings.
As for how much the knee hampered his second half, Chen said, "I can't say that it didn't affect me, but I don't know actually how much. But for this year, I already got it taken care of and I'm going to concentrate on this season and I am going to be ready for the season. And I am not going to think about the knee anymore."
Rays starter Mark Lowe allowed a pair of unearned runs over 2 1/3 innings, giving up four hits over that span. O's center fielder Adam Jones, who scored three runs, doubled to chase Lowe from the game, and he later scored on an errant throw back to the mound by catcher Curt Casali.
Jones also connected for an opposite-field homer to open the bottom of the sixth inning off reliever Steve Geltz, and he pulled off a solo double steal and scored on Chris Davis' team-leading ninth RBI, a single into right field in the first inning.
Orioles reliever Suk-min Yoon went two innings in his second appearance this spring, allowing a solo homer to Jayson Nix in the fifth.
Up Next: Bud Norris will take the mound for Baltimore in a 7:05 p.m. ET road contests against the spring neighbor Pittsburgh Pirates. Steve Johnson, T.J. McFarland and Alfredo Aceves are also slated to pitch, with the Bucs sending Francisco Liriano to the hill.
